Flash floods (or torrential rain flooding) is another type of flood hazard which has caused casualties and significant property damages. A methodology for identification of urban areas, which can potentially be burdened by that type of flood hazard, was proposed. This method, also called Method of Critical Points (CP), is a repeatable process able to identify areas, which are significant in terms of formation of surface run-off and erosion. As addition to the preliminary flood risk assessment according to EU Directive 2007/60/ES on the Assessment and Management of Flood Risks, the presented methodology was applied for the entire area of the Czech Republic and the results are being used for the updating of non-technical measures, e.g. urban planning.
In the article, the principles of methodology of CP are described and results of the first application in the Czech Republic are presented, as well as possible interpretations of them.

Keywords: water erosion, critical point, flood risk, catchment area, porosity, concentrated surface runoff

This paper was elaborated with the support The National Agency for Agricultural Research for the project "New approaches to optimization of systems of integrated area protection in the context of their economic sustainability" [QJ1520268] and project "Erosion processes and their influence on the production capacity of soils and erosion control measures in the design process of land consolidation" [QJ1320157].
